/* Red is a low-luminance color, and luminance is what we need
 * for reading and for detecting fine details. Saturated Red,
 * Orange, Purple should generally be paired with white, and
 * not black. This is true for standard vision but it's doubly
 * true for individuals with certain color vision deficiencies
 * (color blind) particularly protanopia, who see reds much darker.
